SPECIFICATION forming part of Letters Patent No. 353,786, dated December'7, 1886.

Application inea An-i123, ieee.

.T0 all whom it may concern:

Be it known that LFRANK E. HALLADAY@ citizen of the UnitedStates,residing at Plover, in the county of Portage and State ofWisconsin, have invented certain new and useful Improvements inGun-Sights', of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in Which- Figure l represents a perspectiveview of a gun-sight embodying my improvements. Fig. 2 is a longitudinalsectional view of the same.

My invention relates to sights for firearms; and `it comprises aspring-plate, a horizontal screw, and wedge-shaped block for adjustingthe sight, as I shall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I willnow describe lits construction and the mannerin which it is carried out.

In the said drawings,Arepresents a portion of a gun-barrel on which thesight is secured, provided with a dovetailed slot, a, in which is iittedto be adjusted laterally the dovetailed head b of the leaf B. This leafis simply a spring plate rmly held to its engagement with the barrel Aby reason of the dovet-ailed connection before described, and having atits front the projection b, provided with t-he usual sight-notch, b, asshown in Fig. l.

The forward end of the plate B is cut away to form the slot c, withinwhich slides and is guided an inclined or wedge-shaped block, D, havinglugs d d', resting upon the upper surface of the barrel. The lug d isprovided with a threaded perforation, through which passes one endiofthe horizontal screw E, the opposite end of said screw being secured ina ro-v tating nut. e, j ournaled within a slot, f,formed in the head bof the plate B, as shown.

From this description it is manifest the movement of the screw androtating nut in either direction will cause the wedge shaped block toadvance or recede. As said block passes beneath the projecting portion bof theplate or ,the shooting.

which, when once adjusted, is not affected by light winds, head or rearwinds, nor by varying charges of powder, which require a change ofelevation or depression, and which in other sights often so modify theprevious adjustment as to seriously affect the result of I am alsoenabled to obtain elevation for any distance where a spring-sight isused. The sight may also be instantly' changed, does not requirewatching, is readil y operated, and is adapted for all sizes andcalibers of guns,and for light or heavy charges of powder.

Having thus described my invention,` what I claim as new, and desire tosecure by Let-ters l. An improved sight for iire-arms, comprising aspring-plate, B, a block, D, sliding upon the barrel and having aninclined face engaging said plate,and a screw engaging the block,whereby the sight is adjusted.

2. The combination, with the springplate B, one end of which is securedin a slot formed in the barrel, of an inclined or wedge-shapedbloclcsliding upon said barrel, and adjusting the spring-plate, and ascrew and nut for moving the block, substantially as hereindescribed.

3. rlhe combination, with the barrel of a gun provided with a dovetailedslot, of the plate B, having a head fitting within the slot,a slottedforward portion,and a projection, b, asliding block having an inclinedupper face engaging the plate B,a horizontal screw mounted in said plateand engaging a threaded aperture in the sliding block, and anoperating-nut secured to the screw, substantially as herein described.
